The clinical effect of postpartum metritis in female dogs should be achieved after 1-2 courses of treatment. The symptoms basically disappear, no fluid flows out of the vulva, and the estrus is clinically improved. After 2 or more courses of treatment, the symptoms are improved, and there is still a small amount of light-colored fluid in the vulva that is ineffective to be discharged. After 2 or more courses of treatment, the symptoms have not been relieved or slightly aggravated. During the veterinary B-ultrasound examination, a clearer image can be seen on the veterinary B-ultrasound, and the uterine echo is relatively normal.

This disease mostly occurs in Pekingese or crossbreeds with lion dogs, ranging in age from 1 to 4 years old, and there are more cases of blood stasis endometritis. The weak type of qi and blood is second. After treatment, after veterinary B-ultrasound observation, all cured female dogs can basically estrus and mate in time, but the blood stasis type is difficult to cure. The weak type of qi and blood has not been pregnant and produced after treatment. The rest can generally be pregnant and produced smoothly. Veterinary B-ultrasound is generally observed many times during the treatment process to ensure the correct treatment plan.

In addition to the use of antibiotics to fight bacteria and reduce inflammation, the basic principle of clinical treatment for cases of blood stasis and internal obstruction is to activate blood circulation and stop bleeding. The effect of simple hemostasis without distinguishing symptoms is not obvious. Some livestock owners fed Yunnan Baiyao and Gongxuening but the hemostasis was ineffective, which proved the ancient saying of "seeing blood and treating blood". The treatment principle is to activate blood circulation and remove blood stasis, stop bleeding and create new blood. The treatment of Shenghua Tang plus or minus will eliminate all symptoms. It is necessary to observe this treatment process on veterinary B-ultrasound.

Qi and blood deficiency type also shows that lochia is bright red and bloody. This is caused by the spleen not governing blood and blood not returning to the meridians. The treatment principle is to replenish qi and blood, guide blood to the meridians, and select Guipi Tang plus or minus, which has a significant effect. The effect of treatment can also be observed on veterinary B-ultrasound.

From the clinical manifestations, the blood stasis and internal obstruction type is mostly acute postpartum metritis, and the Qi and blood deficiency type is mostly chronic postpartum metritis. The lochia discharged from both syndromes contains blood, either dark red or bright red, which is different from the manifestations of such diseases in cattle and pigs, indicating that canine endometrial inflammation is more prone to hemorrhagic damage. Therefore, in addition to antibacterial and anti-inflammatory treatment, promoting endometrial recovery, promoting blood circulation, removing blood stasis and stopping bleeding, or invigorating Qi and absorbing blood are the keys to treatment, which deserve attention. It is also necessary to observe the recovery of the endometrium through veterinary B-ultrasound.
